The mineral that scratches fluorite but cannot be scratched by glass is apatite. Apatite has a hardness of 5 on the Mohs scale, while fluorite has a hardness of 4, allowing apatite to scratch fluorite. Glass typically has a hardness of about 5.5, meaning it can scratch apatite, but apatite cannot be scratched by glass.
The mineral that can be scratched by glass but not a penny is calcite. Calcite has a hardness of 3 on the Mohs scale, which is lower than the hardness of glass (5.5) but higher than that of a penny (2.5).
If you scratched it then it is surely your problem.
